Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3740CS is determined by strict alignment with the following critical parameters:

Electrical Specifications: Resistance value of 374 Ohms, tolerance of ±1%, and power rating of 0.25W (1/4W) must be identical across all substitute parts.

Package Compatibility: All substitute parts must use the 1206 (3216 Metric) surface-mount package with two terminations to ensure mechanical fit and soldering compatibility on printed circuit boards.

Thermal Characteristics: Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C to 155°C must be maintained.

Composition and Construction: Thick film construction is required for all substitutes.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status to satisfy regulatory and environmental standards.

Substitute parts identified below meet all these criteria and are therefore electrically and mechanically interchangeable with the RCS3216F3740CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

AC1206FR-07374RL (YAGEO) and CRCW1206374RFKEA (Vishay Dale) are recommended as primary substitutes. Both parts maintain Active product status, ensuring long-term availability and continued manufacturer support. AC1206FR-07374RL includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. CRCW1206374RFKEA offers the highest inventory availability (9300 pieces) and also carries AEC-Q200 certification.

Secondary Substitute (Legacy Status):

RC1206FR-07374RL (YAGEO) is an Active product suitable for general applications where automotive qualification is not required. This part is available in Cut Tape and Digi-Reel packaging formats.

Not Recommended for New Designs:

ERJ-8ENF3740V (Panasonic) carries a "Not For New Designs" product status designation. While electrically and mechanically equivalent, this part should not be selected for new circuit designs due to potential discontinuation or limited future support.

Compliance Verification:

All recommended substitutes maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status, ensuring regulatory alignment with the original RCS3216F3740CS component.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-07374RL be used as a direct replacement for RCS3216F3740CS?

A: Yes. AC1206FR-07374RL meets all electrical and mechanical specifications: 374 Ohms ±1%, 0.25W power rating, 1206 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both parts are ROHS3 compliant with MSL Level 1 rating. The primary difference is packaging format (Tape & Reel versus bulk) and the addition of AEC-Q200 automotive qualification on the YAGEO part.

Q: What is the difference between CRCW1206374RFKEA and RC1206FR-07374RL?

A: Both parts are electrically identical 374 Ohm ±1% 0.25W resistors in 1206 packages. CRCW1206374RFKEA (Vishay Dale) includes AEC-Q200 automotive certification and is supplied in Tape & Reel packaging. RC1206FR-07374RL (YAGEO) is supplied in Cut Tape and Digi-Reel formats without automotive qualification. Selection depends on application requirements and packaging preferences.

Q: Why is ERJ-8ENF3740V marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has designated this part for legacy support only. While the part remains electrically and mechanically equivalent to RCS3216F3740CS, new circuit designs should select from Active status alternatives to ensure long-term component availability and manufacturer support.

Q: Are all substitute parts available in the same packaging formats?

A: No. RCS3216F3740CS is supplied in bulk packaging. AC1206FR-07374RL, CRCW1206374RFKEA, and ERJ-8ENF3740V are supplied in Tape & Reel (TR) format. RC1206FR-07374RL is available in Cut Tape (CT) and Digi-Reel® formats. Packaging selection should align with assembly process requirements and inventory management practices.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts listed maintain ROHS3 compliance, MSL Level 1 (Unlimited) rating, and REACH Unaffected status. These certifications ensure environmental and regulatory alignment across all equivalent components.

Q: What is the significance of AEC-Q200 certification on some substitute parts?

A: AEC-Q200 is an automotive industry qualification standard. AC1206FR-07374RL and CRCW1206374RFKEA carry this certification, indicating suitability for automotive applications requiring enhanced reliability testing and quality assurance. The original RCS3216F3740CS and RC1206FR-07374RL do not carry this certification but remain suitable for general industrial and consumer applications.
